The difference between data processor and data controller

As a data controller, you are responsible for deciding the purpose of the data processing and how personal data is processed and stored.

Companies can use suppliers that process personal data, for example a system that then processes the information on behalf of the company.

The data processor and data controller must enter into a data processor agreement setting out the rules and circumstances of the processing.

Checklist for data processors:

Remember a clear data processor agreement with the data controller
The personal data may not be used for any purpose other than the task that you perform for the data controller
When the assignment or underlying commercial agreement is terminated, the personal data must be deleted or returned to the data controller
As a data processor, you must help the data controller to fulfill his obligations under the GDPR
You must provide documentation for compliance with the GDPR, which can be reviewed

To-do list if you are a data controller and use data processors:

You must ensure that you have a legal basis for treatment – read more here
You must have a written, complete and legal data processing agreement
You must supervise all data processors and sub-processors – typically every year

To control data processors and sub-processors, you must either:

Physical supervision of data processor and sub-processor
Request a Processor and Sub-Processor Statement stating that the GDPR and the Processor Agreement are complied with
Maintain control and oversight of data collection from data processor and sub-processor
